Mdmp 1003 03 Ford V8 Engines Hi Po 289

The '65/'66 Shelby version of the Hi-Po 289 was the most impressive "production" configuration for this small-cube overachiever. Teamed with a high-rise aluminum intake, 715cfm Holley, and Tri-Y headers, the engine was rated at 306 horsepower, and made for a strong package in the lightweight G.T. 350.
